lor-skates, and the invention consists in a roller having a peripheral face formed of leather, or the analogous material, of green hide, and in the combination therewith of the devices employed for mounting the leather or green hide. g

In said drawings, Figure 1 is an edge elevation of my improved roller complete for use.

Fig. 2 is a side elevation of the same. Fig. 3

is a longitudinal section of the wheel shown in the preceding figures. Fig. 4 is a transverse section of the same.

Fig. 5 is a view similar to Fig. 2, but showing the supporting-disks united by rivets which pass through theleather parallel with the axis of the roller. Fig. 6 is a longitudinal section of the roller shown in Fig. 5, two of the rivets being shown in elevation, and a cushioning rubber sleeve being also shown in section. Fig. 7 is a transverse section, showing the same parts as are shown in Fig. 6.

In said views, n represents a metallic sleeve, which receives the pivot of the skate, on which the roller. revolves when the skate is in use.

The disks d, which constitute the peripheral sired solidity, and are concentrically mounted eitherdirectly upon sleeve aor upon said sleeve with an interposed body, g,of elastic rubber,

after which disks 7) c arepressed against the against the leather in a suitable press, when the ends of the sleeve are enlarged so as'to produce the riveting thereof, After the leather is thus secured in place between the disks the roller ismounted in alathe and the leather is turned perfectly true and concentric with the axis of the sleeve. When these rollers are to be subjected to severe strain by reason of un usual weight of the person using the skate, or from other causes, I employ, in addition to the means already described for securing disks cl in place, the rivets f, which, passing through the roller parallel with the sleeve and between the-sleeve and the periphery, serve to-so secure the parts together that no severity of strain to which they may be subjected in use will in any degree release the pressure of the metallic disks upon the leather; and said rivets also prevent the possibility of the rotation of the leather between the disks and upon the sleeve in case the latter should not rotate freely upon its arbor. For the purpose of cushioning and muffling the rollers where even a small amount of noise would be objectionable, I employ a sleeve or tube, 9, of elastic rubber, which is arranged upon sleeve on and within disks d, and which servesas the imme- 2 I i I 278,6 6

ing the skate, whileit is preserved from the rapid disintegration which occurs when it is employed as the peripheral face of the roller, besides which, leather possesses an advantage over all other materials of which I have knowledge for such use, in that it gives exactly the desired degree ofhold or contact with the floor, which constitutes an important quality in such rollers.

I claim as my invention-- I l. A skate-roller formed with metallic sleeve (1,, disks 1) 0, and concentric disk-like rings (1', ofleather or green hide, mounted upon said sleeve and compressed between said disks, substantially as specified.

2. A skate-roller formed of the materials andin the manner specified in the preceding claim, and having the securing-rivets f arranged near its periphery, in the manner shown.

3. In a skate-roller formed with metallic 2o sleeve to, disks 1), and the leather or green-hide disk-like rings 61, as specified, the elastic rubbersleeve g, interposed between sleeve a and rings d to cushion the same, substantially as specified.
